‘An idea for storing renewable energy’
was first posted on ccq.org.uk, 25th March 2012

Question “Is it a good idea or barmy?”

Points:

1. There are times when renewable energy cannot be used. Sources tell me that 20% or more of wind energy is grounded (i.e. thrown away) because sometimes the generated energy cannot be used. Other renewable sources (solar, wave power) are also intermittent. Biomass is an exception. Continue reading An idea for storing renewable energy (2012)→

I’ve been studying how temperature has changed over the years in the Arctic. The longest record I’ve got is for land areas only, from the Berkeley Earth Surface Temperature project, which starts way back in 1750:

This was an appendix to Garden Cities and Green Evolutionary Settlements but that’s buried too deep to casually reference. It is reproduced here to show that lifestyles can be affected by a different structure of local finances. I look forward to the Butlins designing Green Evolutionary Settlements to begin the transformation towards more sustainable ways of living.

We need to reduce greenhouse gases in the atmosphere, and we need to do it quickly. The main ones increased by humans are carbon dioxide (CO2), methane (CH4, the main component of natural gas), and nitrous oxide (N2O).

News stories about the Arctic always seem to say either that the Arctic is warming twice as fast as the global average, or that it’s warming nearly twice as fast as the global average. That’s not correct.

Arctic warming is more like three to four times as fast as global warming.
